过山车升降平台的电机同步控制

Multi-motors' Synchronous Control in the Lifting Stage of the Coaster

讨论了过山车升降平台的4台电机之间的同步问题。介绍了给定、主从、虚拟总轴和偏差耦合等控制技术,最终选取了最大偏差耦合同步算法,保证平台各电机在负载不平衡的条件下,具有良好的同步性。

The synchronous control algorisms among 4 sets of the motor equipped in the lifting stage of the roller coaster was discussed. The master and slave control algorism with the deviation control algorism and the max deviation coupling synchronous algorism were introduced. Finally, the latter has been applied into the multi-motors＇ synchronous control to ensure the good synchronous char- acteristic under the condition of unbalanced load on each motor.
